This is scary - take a deep breath before continuing. Place your index finger under the upper left corner of the key and lift up until you hear a click. Then, transfer your finger to the left edge of the key and lift up to pull the key off.

You're freeing the two tabs on the left of the key from the two small holes in the plastic scissors mechanism.

When replacing the keys in the keyboard, place the key directly over the slot where it will go and press down until you hear the key click into place.

Peel up the two pieces of foil tape on the left side of the keyboard area.

The connectors at the ends of the cables are attached very firmly to the sockets on the logic board. Pulling directly on the cable will either separate the cable from its connector or the socket from the logic board.

Carefully disconnect the microphone and power cables from the logic board. Using your fingernails or a dental pick, carefully pry the connectors from their sockets. Make sure you're pulling only on the connector and not on the socket.

At least on my own PowerBook G4 12” 867MHz, the microphone and power cables are long enough that I was able to do the hard drive replacement without disconnecting those connections. I basically had to flip the top case over to the left rather than removing it straight upward. I guess that makes some of the subsequent steps slightly tricky, but at least for me, the tradeoff was worth it.

For step 31 I had a problem where the screws with the springs just kept turning. While I did not have this problem the first time I disassembled the board, it was because I did not tighten the screws on the board (the studs on the actual logic board, not the ones you use to fasten the heat sink to the board) before reassembling. If you encounter the same problem, the screws aren't necessarily stripped but the actual piece attached to the board has become loose and just keeps turning. To get them off I used Vise grips and pulled up while turning until i got them off and it took a while. Moral of the story: tighten the pieces actually attached to the board before reassembling. Sorry, I don't know how else to describe the types of screws used but the stud is attached to the board and that is what came loose.
